2 Claims. (Cl. 7248) This invention relates to improvements in wall forming means for buildings and the like.

An object of 'this invention is to provide a superior air space insulated wall which is adapted to be used for many different types of buildings.

Another object of this invention is to provide dead air space insulated wall construction means which incorporate poured concrete without using the conventional formsl which are afterwards removed.

An additional object of this invention is to provide an air space insulated wall construction which may be easily erected using poured concrete and parts which are fabricated by mass production methods at low cost.

`Another object of this invention is to provide a dead air space insulated wall construction of poured concrete wherein the outer forms which contain the concrete in its plastic state become outer surfaces of the wall construction which may receive a further covering applied in a plastic state.

Additional objects, advantages and features of this invention reside in the construction, arrangement and combination of parts involved in the embodiment of the invention and its.pr actice as will ybe understood from the following description -and the accompanying drawing wherein:

'Figure 1 is a perspective View of a wall section prior tothe introduction'rof concrete therein showing an adjacent'wall sectionv in broken lines;

Figure 2 is a top view of a wall section partly broken away;

Figure 3 is an end view of a'wall section; and

Figure 4 is a-perspective View of apositioning clip member.

VAsshown in Figure l, the wall forming means of the present invention comprises a basicfwall forming unit or plate member designated generally by the numeral 10. Said plate member comprises a shallow pan-like unit having a planar body portion 11 surrounded by a peripheral flange or edge portion 12 comprising horizontal top and bottom flanges 24 and 25 and vertical side flanges 26. The entire plate member 10 may advantageously be formed of a single piece of suitable sheet metal as by a .stamping `and forming operation, the edge portion 12 thereof being formed by bending the borders of said planar body portion intoV planes perpendicular, to the The planar portion 11 of the plate is strengthened by means of vertically disposed 'ridges 13. The plate member is further provided with louvered slots 14 which serve to anchor finishing materials such as plaster, stucco orv cement which it may be found desirable to' apply thereto. Vertical lugs 15 extend from the upper or top ange 24 and are adapted to be received in'v `complementary slots provided in the lower or bottom flange 25. Thus said plate members may be stacked one above the other to any desired height, the plates being firmly retained against displacement by means of said lugs and slot arrangement. The right angular disposition 2,919,572 Patented Jan. k5, 1960 ICC of the peripheral ange 12 with respect to the planar portionll is formed to close tolerances so that the plate members are automatically aligned with one another and results in a plumb Wall structure.

The plate members 10 are held in the desired spaced apart parallel relationship by means of positioning clip members 16 as may be more clearly seen in Figures 3 and 4. Clip members 16 are substantially H-shaped and are formed with generally vertically disposed arms 17 which are connected by means of a narrow horizontally extending cross bar 18 which is disposed substantially medially between the terminal 'portions 19 of said arms 17. The intermediate portion of said cross bar 18 is deflected from the principal plane of said clip body to form a three sided or generally U-shaped clamp portion 20 for the purpose of receiving and supporting insulating sheets in the concavity thereof as will more particularly appear hereafter. The terminal portions 19 of the clip arms 17 are bent at right angles with respect to the principal plane of said clip members 16 and form normally extending lugs 21 which are adapted to be received in registering slots 22 formed in the side flange portions 26 of the plate 10. The lugs 21 are further provided with vertically disposed locking slots 23, the width of each of said slots being adequate to accommodate the thickness of a pair of contiguous flanges 26.

In assembling a number of plate members to form a wall structure the positioning clip members 16 serve to interlock said plate members 10 in spaced apart parallel relationship and to interlock the plate members forming the horizontal extension or course of the wall. Thus, as may be seen more clearly in Figure 2, in assembling the plate members horizontally to form a course, the side flanges 26 of each pair of adjacent plates are placed in contiguity, so that their slots 22 are brought into registration with one another and the lugs 21 of the locking member are then inserted through both slots. A pair of plate members are similarly assembled in parallel spaced apart relation with respect to said rst mentioned pair and the opposing lugs 21 of the locking member are similarly inserted in their registered slots. It is then merely neces- `sary to depress the locking member so that the walls of the flanges 26 are received in locking slots 23 to thereby Y lock the adjacent plate members to one another. To further secure the adjacent plate members the ends of lugs 21 may be bent over as shown in Figure 2. The wall structure may thus be extended horizontally by the successive addition of plate members. The plates at the end of a course may be similarly secured in spaced apart relation by means of a locking member as shown in Figure 1. v

The insulation for the Wall structure is accomplished by the incorporation of a pair of panels between 'the spaced apart plate members. The insulating panels 27 are preferably of thermal insulation material such as U-shaped concavity 20 formed in cross bar 18 compris ing a clamp. The insulating boards 27 are limited in width by the length of the plate members between which they are disposed by reason of the interposition of the positioning clips but they may extend upwards as far asdesired as they are not limited by the height of individual plate members, and may extend as high as the wall being constructed. The insulating boards and a spacing strip are preferably tacked, nailed, glued or otherwise fastened together prior to insertion. The clamp portion 20 of the clip member 16 is dimensioned to snugly receive and therefore firmly retain the spacer strips and consequently the panels which are secured thereto. The panels and spacers may be additionally secured to each other after insertion if desried. In order to achieve a more accurate alignment of each pair of insulating panels, an indentation may be formed in one of their confronting end edges as shown at 29 to allow for the thickness of the wall of the clamp portion 20.

It will be apparent from the foregoing that there is thus achieved a skeletal wall structure wherein the wall is defined by means of a series of parallel spaced apart substantially planar metallic plate members and that an insulating assembly of suitably spaced apart and secured insulating panels is rnedially disposed in spaced relation with respect to said plate members. The insulating assembly of spaced apart insulating panels forms a dead air space, adds materially to the insulation characteristics thereof and forms a significant feature of this invention. In order to impart the requisite ultimate structural characteristics to the skeletal structure, as above defined, concreteis poured into the space between the insulating panels and the confronting plate members. The wall structure having the concrete thus incorporated therein is illustrated in Figures 2 and 3. The concrete 30 may be of suitable composition for the particular bearing and structural characteristics required and may be poured after the entire skeletal wall arrangement has been assembled or in progressive courses as the skeletal structure is assembled. It should however be noted in all events that the concrete layers thus comprise the interior and exterior wall portions which are spaced apart and partitioned by the intermediate insulating assembly comprised not only of panels of insulating material but of an intermediate dead air space coextensive with said wall and having therefore excellent insulating characteristics. The cross bars 18 of the positioning clips 16 are relatively narrow and provide negligible heat conduction between the opposing wall surfaces. The entire skeletal arrangement is securely interlocked against displacement during the concrete pouring operation and adds to the rigidity and strength of the ultimate wall structure. Furthermore surface finishing materials may be applied directly to the exposed surfaces of the plate members.

I have here shown and described a preferred embodiment of my invention. It will be apparent, however, that this invention is not limited to this embodiment and that many changes, additions and modifications can be made in connection therewith without departing from the spirit and scope of the invention as herein disclosed and hereinafter claimed.
